Two Formula Mass Calculations 2

Empirical Formula:

This is just how you can find out the number atoms for each element in a compound. To do this, first list all the elements in the compound and how much of them there are (in grams). Then, divide each of the masses of each element, by a single mole of the element. Then, divide all the values you get after the calculations, by the smallest value you get. Here is an example:
